I am thinking something like this.You will have to let me know what elevation you want the sun. It's best not to be directly overhead so that there are some shadows to show the terrain better. And you will have to let me know how far off the sand you want the camera, this is a meter or two above. I suspect you might want the camera higher.Because of the volumetric clouds, these renders take over 8 hours each for me. Constructive feedback please!

Thanks! Feel free to give me more specifics about positioning of the sun, for example. I see that it has been suggested to put the sun up high. I can do that of course if you like, but it will made the terrain less detailed.

Also, let me know when you would like delivery of a draft set of images to be assembled into the box so I can prioritize with other projects.
